Answer 2

Step-by-step explanation:

  Total no. of possible outcomes = 89 {2, 3, 4, …., 90} (i) Let E ⟶ event of getting a 2 digit no. No. favourable outcomes = 81 {10, 11, 12, 13, ….., 80} P(E) = (No.of favorable outcomes)/(Total no.of possible outcomes) = 81/89 (ii) E ⟶ event of getting a no. which is perfect square No. favourable outcomes = 8 {4, 9, 16, 25, 36, 49, 64, 81} P(E) = 8/89Read more on Sarthaks.com - https://www.sarthaks.com/102300/contains-cards-which-numbered-from-card-drawn-random-from-find-the-probability-that-bears
